Fig. 4

Scatter plots of the maximum core temperature decrease and the preoperative toe PI, and the predicted curve fitted by SRM and GAM. Maximum core temperature decrease: the difference between the core temperature at OR admission and the minimum intraoperative core temperature. SRM: segmented regression model; GAM: generalized additive model; OR: operating room; PI: perfusion index
